10 Introduction 1 NI-FBUS Monitor Overview This chapter contains an overview of the NI-FBUS Monitor. The NI-FBUS Monitor is a Win32 application used to monitor, debug, and analyze fieldbus data packets. The NI-FBUS Monitor detects communication on the bus, capturing data packets that are passed between fieldbus devices. These packets are time-stamped and displayed in real time in active packet view of the NI-FBUS Monitor. The NI-FBUS Monitor can display data packets in decoded format or in hexadecimal format. The NI-FBUS Monitor can filter out unwanted data packets at three levels: the Fieldbus Data Link layer (FDL), the Fieldbus Messaging Specification layer (FMS), and by fieldbus addresses. Windows of the NI-FBUS Monitor The NI-FBUS Monitor has a Multiple Document Interface (MDI). An MDI window contains many smaller windows open concurrently that display data from different sources. These smaller windows are called filter windows. In the NI-FBUS Monitor, some filter windows might contain previously-captured data, while other filter windows might capture new data from different buses or the same bus. Chapter 3, Windows and Menus, lists and describes the windows of the NI-FBUS Monitor. Recommended Minimum Platform The recommended minimum platform for the NI-FBUS Monitor is a 66 MHz 486 processor with 8 MB of RAM. If you want to run the NI-FBUS Monitor on a slower platform, refer to the Improving Performance section of Chapter 4, How To Use the NI-FBUS Monitor.

The main window is the large desktop window that contains all other windows of the NI-FBUS Monitor. It has a menu bar and various toolbars. The smaller windows inside the main window are filter windows. Each filter window uses a single filter to determine what data the NI-FBUS Monitor captures. The main data object that stores these captured data packets on a disk and holds the data in memory is called the capture document. You can use the filter window to view the data in the capture document. You can attach several filter windows with the corresponding filters to the capture document. When you select New from the File menu, the NI-FBUS Monitor creates a new capture document and a corresponding filter window. The filter window displays data from the capture document. Each filter window has an exclusive filter attached to it that you can view as a dialog box. To display the filter, select Filter Settings from the Capture menu. You can use the filter to determine what data the NI-FBUS Monitor displays in the filter window and what data it saves to the capture document. To add a new filter window to the document, select New Filter Window from the Capture menu. Adding a new filter window attaches a new filter window and filter to the document. You can use the new filter to filter different data. Figure 3-1 is a graphical example of the relationships between the windows and the document. The gray area represents the graphical area that appears on the desktop. The documents on the left are data objects invisible on the desktop. Note Even if a window is split using the Split Filter Window function, the filter window still has only one filter attached to it. NI-FBUS Monitor User Manual 3-2 ni.com

Filters Filter Operation During Capture Filter Operation After Capture The filter is a tool you can use interactively at capture time or after capture. During capture the filter is valid, and the NI-FBUS Monitor discards all data not matching the filter. However, if there are multiple filter windows, the NI-FBUS Monitor checks each filter to make sure that it retains the desired data. If you make changes to the filter, the NI-FBUS Monitor instantly downloads the changes to the fieldbus, so the changes take effect immediately. After capture, you can filter out more undesired data (postfilter) by selecting only the packets you want to view. Changes to the filter forces the NI-FBUS Monitor to refilter the data, so that only the selected packets are visible. The NI-FBUS Monitor retains all of the original captured data.

28 Chapter 3 Windows and Menus refilter the data and display the desired packets, click on the packet types that you want to view again. The data filtered out during capture is not accessible. For example, after capture, you cannot recover Pass Token (PT) FDL packets if they were not enabled during capture. Basic Filter Logic A filter behaves differently depending on whether you select addresses on the Filter by Address tab. If no addresses are selected, the filter uses all addresses and combines the FDL Filter and FMS Filter choices, and captures the types of packets checked in those dialog boxes. If any addresses are selected on the Filter by Address tab, incoming packets are first screened for their address. If the address is one of the selected addresses, it is then compared to the FDL filter and the FMS filter. Pseudocode for the filter follows: If no addresses are selected in the Filter by Address tab: Packets Captured = FDL Filter + FMS Filter If addresses are selected in the Filter by Address tab: Packets Captured = Address(es) * (FDL Filter + FMS Filter) where + stands for or and * stands for and. Filter Dialog Box To view the Filter dialog box for a filter window, right-click the mouse to bring up the Capture menu and select Filter Settings, or you can click the Filter Settings toolbar button. The title bar of a filter displays the name of the filter window to which it is attached. The filter appears as a dialog box with three tabs FDL Filter, FMS Filter, and Filter by Address. You can open the Filter dialog box any time before, during, and after capture, or you can hide it from view. The following sections describe the tabs on the Filter dialog box.

36 Chapter 4 How To Use the NI-FBUS Monitor Saving Data To save the captured data, select Save from the File menu or click the Save Capture button on the standard toolbar. The NI-FBUS Monitor places the saved data in the current window. During the save operation, the NI-FBUS Monitor prompts you to save all of the captured data or just the filtered data, if there was any filtering after capture. You can save data in two formats: *.mon, a binary format that the NI-FBUS Monitor can reload and refilter *.txt, an ASCII format that text editors can load Finding Data To find data, select Find Data from the Capture menu or click the Find Data button on the standard toolbar. The Find dialog box, as shown in Figure 4-1, appears. If the NI-FBUS Monitor finds the data, it places an elliptical mark by the packet in which the data appears. Figure 4-1. Find Dialog Box Viewing Data You can view data in a filter window, and switch between tabs to view all the information, or you can split the window and view all tabs simultaneously. To split the current Filter window into four panes, select Window»Split Filter Window or click the Split Filter Window button on the standard toolbar. The split window allows you to look at different parts of the capture at the same time. Figure 4-2 shows an example Filter window screen split into four panes that display the data for this filter.

38 Chapter 4 How To Use the NI-FBUS Monitor Note Only NI-FBUS Monitor version 4.0 or later supports the simulator. Improving Performance Conserve Memory Turn Live Updates Off Filter Only for Needed Data This section contains hints for improving the performance of the NI-FBUS Monitor on systems slower than the platform recommended mentioned in the Recommended Minimum Platform section of Chapter 1, Introduction. Close unnecessary applications, and set Max num of packets on the Capture Settings tab to a low value (less than 500). To see the Capture Settings tab, select Capture»Settings or click the Capture Settings button on the standard toolbar. To prevent the NI-FBUS Monitor from updating its windows, deselect Live Updates on the Capture menu. On a slow computer, it can take a relatively long time (more than one second) to update the graphics in windows. During this time, you can lose many data packets. Lost packets are denoted by an asterisk (*) before the packet in the capture. Pass Token (PT), Time Distribution (TD), Return Token (RT), Probe Node (PN), Probe Response (PR), and Compel Data (CD) packets occur frequently. You might not want to collect all of these, particularly the Probe Node (PN) packets. No Split Windows In general, the fewer open windows the NI-FBUS Monitor has to update, the faster the NI-FBUS Monitor performs. NI-FBUS Monitor User Manual 4-4 ni.com
